Definitions

  • the present invention relates to a system which provides the joining of frame profiles and interconnection profiles of doors, windows, and similar structures, by means of friction welding.
  • One of the widely-used methods for coupling interconnection profiles into the frames is the screw-connection method.
  • two ends of a an interconnection profile are previously milled at a profile fitting machine according to the form of the internal surface by which it is to be fit into the frame. It is then screwed to the frame by making use of various connection elements.
  • two ends of an interconnection profile are tapered in a " ⁇ "-like shape, whereas a slot or recess is opened on the frame in a "V"-like shape. The opened slot and tapered sections are brought together by means of heating in a "V” welding machine. Any burrs resulting from the welding operation are cleaned by special machines.
  • the screw-coupling method requires longer periods of time for the assembly work, additionally causing defective assemblies due to incorrect sizes, and demanding an excessive amount of connection elements.
  • the resistance heating method four separate machines are employed for cutting the ends and edges, and for welding and cleaning, this method also requiring longer periods of assembly time as compared to the screw-coupling method.
  • the patent document No WO 2005/009664 discloses a multi head friction welding method and a device for carrying out the method. Said method is related to the welding of joining surfaces of shaped parts. Under the influence of the friction welding heads, the individual shaped parts and said joining surfaces are aligned with one another and the joining surfaces are pressed together and the free ends of said shaped parts on both sides of the joining surfaces are set into vibration by means of eccentric shafts.
  • the patent document No EP 1 932 650 A1 discloses a method for the production of a mitered corner joint between two components by vibration welding. During the welding process, the two components are set into mutually perpendicular straight-line translational oscillations and the phases are matched to each other to provide the oscillation of miter areas of the components at right angles.
  • patent document No WO 2007/131358 A1 discloses a welded joint structure for thermoplastic members.
  • An interposed junction piece vibratory is welded to a first and second member at respective welding surfaces. Between unwelded portions of the first and second members, the welding surface of the first member and the welding surface of the second member form an angle in a plane normal to the interposed junction piece.
  • the patent document No DE 296 05 394 U1 A discloses a welding machine for the production of window frames.
  • the invention uses a rack with at least six welding heads for welding parts of each frame and a welding mirror with a respective angle.
  • thermoplastic profiles are heated to a welding temperature.
  • the welded profiles are subjected to cutting process.
  • the patent document No DE 21 10 540 A1 discloses a further example; a frame welder with four clamp members for plastic frames.
  • the clamp members are placed at right angles with respect to each other. Two of the clamp members are able to move together to carry out the welding process and the other two, which are oppositely placed, are arranged to be stationary during welding.
  • patent document No EP 1 338 404 A2 discloses a device and a process for welding plastic profiles with at least two carriages to hold the profiles; stoppers for adjustment and welding; and a heating element.
  • the invention is based on the fact that two plastic profiles connected to each other, move against each other or one plastic profile stops and the other moves toward it. By this way, the control of the motion of the plastic profiles by a device is provided during welding process.
  • the patent document No DE 41 38 501 A1 discloses a multi-position welder.
  • the basic feature of the invention is that the mounting of the positioning surfaces on a plane and said surfaces can be rotated relative to the welding head along a vertical axis. Moreover, the welding head and the positioning surfaces can also be rotated at a relative degree.
  • materials to be joined are brought together to produce high-frequency mechanical friction in between, the resulting heat melting the materials to some extent, such that they are welded and the joining of profile corners completed.
  • the profile joining system As for the profile joining system according to the present invention, it is developed for joining an interconnection profile (i.e. meeting rail profile) into a frame by means of friction welding.
  • the system comprises in general terms a stand onto which a frame is situated; front and side thrusts onto which the side profiles, i.e. jambs, of the frame are leaned; at least one clamp, disposed on the front thrust and clamping at least one side profile; at least one positioning element adjusting the position of the interconnection profile, i.e. meeting rail; and at least one retainer block, used for keeping the interconnection profile immobilized.
  • the frame and the interconnection profile are joined temporarily before processed in the system.
  • the interconnection profile is tightly fit in between two side profiles of the frame.
  • the butt surfaces of the interconnection profile are brought in contact with the side surfaces of side profiles. These contact surfaces are the surfaces onto which friction welding is applied.
  • the butt surfaces of the interconnection profiles are processed according to the geometrical structure of the side surface of side profiles so as to give the most proper contact surface for welding.
  • the position of the interconnection profile is adjusted with respect to the frame and the frame is immobilized with the help of mobile and/or stationary trust(s), as well as guiding apparatuses.
  • the interconnection profile is thus supported by means of various retainer blocks.
  • the objective of the present invention is to provide a system which provides the joining of an interconnection profile in between two opposite profiles of a frame by means of friction welding.
  • Another objective of the present invention is to prevent any burr formation at the joint during the friction welding process conducted by means of said system, thereby obtaining a neat-appearing joint.
  • a further objective of the present invention is to ensure an accurate adjustment be made for the position and angle of the interconnection profile with respect to the frame profile.
  • Still another objective of the present invention is to provide a system, which performs said welding operations in a rapid, inexpensive, and reliable manner.
  • Profile joining system (A) Frame (1) Side profiles (1 a, 1b, 1 c, 1 d) Interconnection profile (2) Front thrust (3) Claim (4) Side thrust (5) Side thrust (6) Stand (7) Positioning guide (8) Retainer block (9) Jaws (9a, 9b) Base plate (10) Vibration unit (11) Brake mechanism (12) Press (13) Press (14)
  • the profile joining system (A) is developed for joining an interconnection profile (2) into a frame (1) by means of friction welding.
  • the system (A) comprises in general terms a stand (7) onto which a frame (1) is situated; front and side thrusts (3, 5, 6) onto which the side profiles (1a, 1c, 1d), i.e. jambs, of the frame (1) are leaned; at least one clamp (4), disposed on the front thrust (3) and clamping at least one side profile (1a) (the clamps (4) can also be arranged so as to clamp the other side profiles (1b, 1c, 1d)); at least one positioning guide (8) adjusting the position of the interconnection profile (2), i.e. meeting rail; at least one retainer block (9), used to keep the interconnection profile (2) immobilized where it is situated; and at least one vibration unit which provides the joining of the interconnection profile (2) to the frame (1) by means of vibration.
  • the frame (1) and the interconnection profile (2) are joined temporarily before put into the system (A). During this joining operation, the interconnection profile (2) is tightly fit in between two side profiles (1c, 1d) of the frame. Thus, the butt surfaces of the interconnection profile (2) are brought in contact with the side surfaces of said side profiles (1c, 1d). These contact surfaces are the surfaces onto which friction welding is to be applied.
  • the butt surfaces of the interconnection profiles are processed according to the geometrical structure of the side surface of side profiles (1c, 1d) so as to obtain the most proper contact surface for welding.
  • the temporarily-joined frame (1) and interconnection profile (2) is placed on the stand (7), so that one side profile (1a) of the frame (1) is leaned against the front thrust (3), and the combination of the frame (1) and interconnection profile (2) is thus put into the system (A).
  • the system (A) is further provided with two side thrusts (5, 6) in order to adjust the position of the frame (1), so that while one side profile (1c) is leaned against the first side thrust (5), the other opposite side profile (1d) is rested against the second side thrust (6).
  • At least one clamp (4) is provided on the front thrust (3) (the clamps (4) can alternatively be arranged to clamp the other side profiles (1b, 1 c, 1 d)), such that the side profile (1 a), which is leaned against the front thrust (3), is clamped by means of this clamp (4).
  • said side profile (1a) is immobilized on the front thrust (3).
  • the front thrust (3) is a component that can be displaced forth and back (directions a-b) with an adjustable positioning. Thanks to this feature, it becomes possible to adjust the position of the frame (1) in for- and backward directions (a-b) within the system (A).
  • the forth and back displacement (directions a-b) of the frame (1) allows to adjust the position of the interconnection profile (2) as well.
  • at least one positioning guide (8) is disposed in the system (A), which is capable of displacing at down- and upward directions (e-f).
  • the positioning guide (8) is displaced upward without displacing the front thrust (3) and is raised to the side of the interconnection profile.
  • the frame (1) and profile (2) are moved together until leaning against the guide (8) with the displacement of the front thrust (3).
  • the profile (2) is leaned against the guide, the movement is terminated; but the displacement of frame (1) is continued until it arrives at the desired position.
  • the position of the profile (2) with respect to the frame is adjusted.
  • the frame (1) now brought to the desired position, is taken to the welding position by displacing the stand (7) downward (the stand (7) can displace at down- and upward directions (e-f)).
  • the interconnection profile (2) becomes situated into the retainer blocks (9).
  • the retainer blocks (9) are placed close to both ends of the profile (2).
  • the inner surface of the blocks (9) is formed so as to rest onto the side surface of the profile (2).
  • Each block (9) is equipped with two jaws (9a, 9b), at least one of the jaws making a back-/forward displacement (directions a-b) (see figures 4 and 5 ) both to open/close the block and to tightly immobilize the profile (2).
  • the frame (1) is positioned between one front thrust (3) and two side thrusts (5, 6).
  • the side thrusts (5, 6) can either be stationary, or at least one of them can be arranged to displace at right-left directions (c, d) for welding frames of different widths. In this manner, the frame (1) is immobilized between both the front thrust (3) and the side thrusts (5, 6).
  • the profile (2) and the frame (1) are joined together permanently by means of friction welding.
  • the base plates (10) (see figures 4 to 6 ), to which the retainer blocks (9) are coupled, are vibrated under high frequency at for-/backward directions (a-b).
  • the displacement of base plates is provided from the vibration unit (11) (see figures 3 to 6 ) to which they are coupled to.
  • the vibration process can either be performed linearly at for-/backward directions (a-b), as is the case above, or in a rotational, or orbital manner.
  • one press (13) exerts force on the frame leftward (d) from below a side thrust (5), while the other press exerts force on the same frame rightward (c) from below the second side thrust (6).
  • the direction of exerted press force is kept similarly along the profile (2), so that while the profile (2) is exposed to vibration, it is fit into the frame (1) in a robust manner.
  • the press force of the presses (13) can be adjusted according to the material and strength of the profiles subjected to friction welding.
  • one extra press (14) (see Figure 4 and Figure 6 ), one each arranged at each welding site, is also disposed in the system (A).
  • presses (14) prevent burr formation by exerting press from above on the joining sites of the profile (2) and frame (1), while the friction welding process is in progress. Accordingly, the operation direction of said presses (14) arranged in the system (A) are the up-/downward directions (e-f). The press exerted by the presses prevents the upward flow of burrs.
  • the press force of the presses (14) can likewise be adjusted according to the material and strength of the profiles subjected to friction welding. Additionally, the activation time of presses can be set according to the formation of burrs.
  • Another feature of the system (A) is that the mobile jaws (9a, 9b) of the retainer blocks (9) are tightened by means of a brake mechanism (12), so that the positions of blocks (9) on the respectively coupled-base plates (10) are fixed. Said jaws (9a, 9b) are tightly clutched by means of hydraulic or hydro-pneumatic brake mechanisms so that they cannot be opened during the vibration process. Thanks to this feature, the retainer blocks (9) are enabled to clamp the interconnection profiles (2) in a sound manner.
  • the system (A) is also provided with at least one fastening tab, which exerts press to at least one of the side profiles (1c, 1d). Since the tips of these fastening tabs are tapered, they form recess-shaped traces on the points of the profiles (1c, 1d) to which they rest, assisting in maintaining the positions of profiles (1c, 1d) while they vibrate. Said fastening tabs are activated once the frame (1) is positioned, and are released back from the profiles following the welding operation.
  • all mobile units such as the stand (7), thrusts (3, 5, 6), presses (13, 14), brakes (12), guides (8), retainer blocks (9), vibration units (11), as well as the mobile subparts thereof can be driven by means of motors, pumps, etc.; and various sensors can be used for positioning the frame (1) and the profile (2).
  • the operation of the system (A) can be arranged by means of a separate control unit. Following the completion of the welding operation, all said mobile parts are restored to their initial positions (to their positions, before the frame is positioned).
